Mollie and Harry were linked after they were seen dancing the night away at Bunga Bunga karaoke bar in London last month.

The 24-year-old said her bandmates were excitedly joking about what it would be like visiting Harry’s “nan” for lunch at Buckingham Palace, before adding: “I just went out with loads of friends, there were loads of us, and all of a sudden we’re an item – but we’re not.”

Bandmate Frankie Sandford, who is dating footballer Wayne Bridge, joked: “To be fair, when we heard the rumours we were all worried, thinking if she became royal we’d all have to change around her, wouldn’t we?”

Meanwhile, Mollie also revealed she struggles to speak to men when she fancies them, because she lacks confidence.

“I can’t flirt,” the shy singer said. “I get embarrassed if I really fancy somebody. I can’t look them in the eye.

“I’m just not great sometimes – if I don’t fancy somebody I’m fine. I actually think I’m not great generally at flirting.”

Mollie recalled a time when she was with Vanessa White when a guy was texting her bandmate.

She said: “Vanessa didn’t know what to reply to him.

“I helped her send one, and he didn’t reply after that.

“She said she’s never doing that again.”

The Saturdays, who last month premiered their new single 30 Days, have been on a short break from performing after Una Healy gave birth to her first child, Aoife, in March.

Molly said: “Una’s new little girl is so cute, she’s so adorable.

“You can imagine what we’re like, having babies and getting married, it’s such a girly atmosphere right now.”

Una, 30, and rugby star fiance Ben Foden posted a picture of their new arrival on Twitter this week.

And, after returning to work, she is clearly missing Aoife.

She sent Ben a tweet: “Give her a massive kiss and hug from me. I won’t be too late, hopefully!”
